SPECIFICATION forming part of Letters Patent N0.406,295, dated July 2, 1889.

Application filed March 23, 1889- Serial No. 304,469. (No model.)

To aZZ whom it may concern:

Be it known that I, JOSEPH MOLEAN, a subj ect of the Queen of Great Britain, and a resident of Rockville, in the county of Tolland and State of Connecticut, have invented certain new and useful Improvements in Clip- Molds, of which the following is a full, clear, and exact description, whereby any one skilled in the art can make and use the same.

The object of my invention is to provide a mold for making a tag or clip for use in pipe- Work and means for rapidly and cheaply producing the clip; and to this end" my invention consists in the mold having the several features of adjustment by means of which the clip may be made of different sizes to fit pipes of different diameters; and it further consists in details of the several parts of the device and their combination, as more particularly hereinafter described, and pointed out in the claims.

Referring to the drawings, Figure 1 is a detail plan View of the under side of one of my improved clips, shown as holding a pipe. Fig. 2 is a detail view in cross-section of a pipe and tag, illustrating the method of using the old style of tag for the purpose of securing pipes Fig. 3 is a detail top view of a pipe held by my improved clip. Fig. 4 is a detail view in cross-section of the same. Fig. 5 is a detail side view of the clip-mold with parts broken away to show construction, and on reduced scale. Fig. 6 is a detail face view of the right-hand mold-face. Fig. '7 is a detail face view of the left-hand mold-face. Fig. 8 is a detail view in lengthwise central section of the mold, with parts in position for casting the clip. Fig. 9 is a detail view in lengthwise central' section of the mold with parts in position for casting a long clip.

In the accompanying drawings, the letter a denotes a pipe 5 b, a tag such as is in common use, the tag being soldered to the side of a pipe and used to hold the latter in any desired position along a fixed surface. The letter 0 denotes a clip that consists of a central part c, that is curved to partly fit upon a pipe a, and has the feet 0, that extend upon. opposite sides of the pipe, and are provided with holes through which the fastening devices may be driven. The old form of tag has two screw-holes, one on each side of the clip.

I11 using my improved clip to secure a pipe, as to a wall, it is placed across the pipe so that the feet portions rest against the surface along which the pipe lies, and screws or nails are driven through the holes in the feet portions. If it is desired to solder the clip to the pipe, the opening d in the center of the high est part of the clip may be used for the reception of the solder, and a firm connection made between the clip and the pipe at this point.

As the pipes differ in diameter, it is 11eces= sary to furnish clips of varying lengths, measured from the inner edge of the feet portions, and my improved'mold e, that is used for the purpose of casting theclips, is provided with adjustable parts that enable the clips to be cast with any desired length of metal between the inner edges of the feet or base part of the clip. The curvature of the clips formed in the mold is of course always the same; but as they are cast of lead, tin, or alloys of such metal that fuse at a comparatively low temperature and are easily bent,'the clip after being cast is set ast-ride the pipe to be fastened by it, and the straight parts readily bend to the contour required, as the curved part is easily sprung open to fit a pipe of larger curvature at the top of the pipe. A clip having longer straight parts, such as could be made with the mold set as shown in Fig. 9, produces enough length of metal between the feet portions of the clip to enable the clip to be used on a pipe of larger curvature than is the case with a clip having shorter straight portions, such as would be cast when the molds are arranged as shown in Fig. 8.

The mold is madenp of an outer hollow shell f, that is made in two parts f f united at the flat portions formed by the flanges f and within these shells are supported the sliding cores 9 g. The recesses of the mold that form the feet-pieces of the clip are made in the adjacent faces of the flanges, while that part of the clip that is rounded is formed between the convex end of one of the sliding cores g and the concaved or recessed end of the opposite core g. There are two parts f that project from the upper and lower inner walls of the shell f into the grooves 'i i, respectively, into which they fit closely, so as to form a corner at the feet portion of the clip and close the groove against the flow of molten metal back along the core, and this limits the flow to the parts between the flanges in which the feet portions of the clip are formed, the curved part between the adjacent ends of the cores, and that part of the grooves 11 11 that is located between the feet and the curved part of the clip. These two cores are adj ustable lengthwise along the shell, so that their meeting faces may be moved to a considerable distance beyond the plane of the meeting faces of the flange, and they are held in any fixed position by the clamp-screws 7b 71 respectively. hen the mold is fitted, as shown in Fig. 8, the parts are adapted to cast a clip that will fit upon the smallest diameter of pipe, and in order to adapt the mold to fit a larger size of pipe the cores are slid toward the right within the shell, the groovesi t of the core 1 forming a continuation of the parts j j of the mold and connecting with them the rounded portion j". In order to enable the mold to be set to cast any desired length of clip, the edge of one of the cores, as g, is provided with a scale 70, that is marked to any convenient degree of graduation.

For convenience in handling, one or both of the cores maybe provided with a handle Z, while the shell of the mold may be held as in a vise, or be secured to a fixed object, as a bench, by means of screws or otherfastenin g devices.

The in gate is formed in any convenient position along the plane of the meeting Faces of the flat portions of the mold.

I claim as my invention 1. In combination, in a mold, the sectional shell-pieces and the sliding cores borne in the respective shell-sections, the meeting faces of the shell-sections and cores being hollowed to form a chamber, all. substantially as described.

2. In a mold, in COlllbllltLtlOll with the sectional shells f f the sliding cores 1 q and the clamp-screws 7t 72 for holding the cores against sliding movement in the shells, all substantially as described.

3. In combination with the shells f f the sliding cores g g, borne in the respective shell-sections, the core 9, having the channels it, forming a connection between the several parts of the mold-chamber when the core is in the several positions of its adjustment, all substantially as described.

l. In a mold, in combination with the sectional shellsf f having the meeting faces crosswise of the shells, the sliding cores 9 and g and the clamping devices h 71 for holding the cores against sliding movement within the respective shells, one of the cores bearing a graduated scale, all substantially as described.
